server and it must be reachable for automatic update and global correlation updates to be successful. You can configure other DNS servers as backup servers. DNS queries are sent to the first server in the list. If it is unreachable, DNS queries are sent to the next configured DNS server.

Caution For automatic and global correlation updates to function, you must have either a DNS server or an HTTP proxy server configured at all times.

Caution DNS resolution is supported for accessing the global correlation update server as well as www.cisco.com for automatic updates.

The following options apply:

•http-proxy {no-proxy proxy-sensor}—Configures the HTTP proxy server:

–address ip_address —Specifies the IP address of the HTTP proxy server.

–port port_number —Specifies the port number of the HTTP proxy server.

•dns-primary-server {enabled disabled}—Enables a DNS primary server:

–address ip_address —Specifies the IP address of the DNS primary server.

•dns-secondary-server {enabled disabled}—Enables a DNS secondary server:

–address ip_address —Specifies the IP address of the DNS secondary server.

•dns-tertiary-server {enabled disabled}—Enables the DNS tertiary server:

–address ip_address —Specifies the IP address of the DNS tertiary server.

Configuring DNS and Proxy Servers for Automatic Update and Global Correlation

To configure DNS and proxy servers to support automatic update and global correlation, follow these steps:

Step 1 Log in to the sensor using an account with administrator privileges.

Step 2 Enter network settings submode.

sensor# configure terminal

sensor(config)# service host

sensor(config-hos)# network-settings

Step 3 Enable a proxy or DNS server to support global correlation:

a.Enable a proxy server.

sensor(config-hos-net)# http-proxyproxy-serversensor(config-hos-net-pro)# address 10.10.10.1 sensor(config-hos-net-pro)# port 65 sensor(config-hos-net-pro)#

b.Enable a DNS server.

sensor(config-hos-net)# dns-primary-server enabled sensor(config-hos-net-ena)# address 10.10.10.1 sensor(config-hos-net-ena)#

Step 4 Verify the settings.

sensor(config-hos-net)# show settings network-settings
